Packets per second (PPS) is a network measurement that quantifies the number of individual data packets transmitted through a network interface each second. In cybersecurity, PPS is a critical metric for assessing the intensity of network traffic, especially during events like Distributed Denial of Service (DDoS) attacks. High PPS rates can overwhelm network devices, leading to degraded performance or outages. Monitoring PPS helps security teams detect abnormal traffic patterns, respond to attacks, and ensure network stability. Unlike bandwidth, which measures data volume, PPS focuses on the frequency of packets, making it essential for evaluating threats involving numerous small packets.
